The move comes after running back Chris Thompson, who is listed as the third running back on Washington’s depth chart, sustained a torn labrum in the Redskins’ 19–16 loss to the Dallas Cowboys on Monday.

Thomas, a nine-year veteran, spent eight seasons with the New Orleans Saints before signing with the San Francisco 49ers this year. This season, Thomas also worked out with the New England Patriots after the 49ers released him on Nov. 10.

Thomas, 30, caught a total of 389 passes for 2,608 yards with the Saints. In 2009, he lead the Saints in rushing, and recorded career highs in yards (793) and yards per carry (5.4), while also picking up six touchdowns.

In Thomas’s only game with San Francisco this season, he had four carries for 12 yards against Atlanta.
